Feinstein Institutes for Medical Research

The Feinstein Institutes for Medical Research in Manhasset, Nassau County, New York, United States, on Long Island, constitute the research arm of Northwell Health. Feinstein is home to 50 research labs, 2,500 clinical research studies, and 5,000 professional and support staff. Feinstein scientists conduct research in molecular medicine, genetics, cancer, brain research, mental health, autoimmunity and bioelectronic medicine, among others. Feinstein is the laboratory and faculty home of the Elmezzi Graduate School of Molecular Medicine. Students with an MD degree may earn a PhD in molecular medicine via the Zucker School of Medicine, as part of the medical school's MD/PhD or PhD programs.

The Feinstein Institutes acquired assets from the closing of the Picower Institute for Medical Research, founded in 1991 by Anthony Cerami and funded by Jeffry Picower. In 2001 the institute's funding was withdrawn and it closed; in 2002 it was acquired by The Institute for Medical Research at North Shore-LIJ. In 2005 board member Leonard Feinstein, co-founder of Bed Bath & Beyond, made a $25 million gift that led to its renaming The Feinstein Institute for Medical Research. In 2017, Feinstein and his wife, Susan, committed another $25 million.

In 2024, Feinstein Institutes for Medical Research comprises the following five institutes:
 * Institute of Behavioral Science, led by John Kane, MD and Anil K. Malhotra, MD.
 * Institute of Bioelectronic Medicine, led by Yousef Al-Abed, PhD and Lopa Mishra, MD.
 * Institute of Molecular Medicine, led by Betty Diamond, MD.
 * Institute of Cancer Research, led by John Boyd, PhD.
 * Institute of Health Systems Science, led by Karina W. Davidson, PhD, MASc.

Feinstein publishes two open-access, international peer-reviewed medical journals in partnership with BioMed Central, part of Springer Nature: Molecular Medicine and Bioelectronic Medicine.

The Feinstein Institutes bestow two major academic awards: the Anthony Cerami Award in Translational Medicine, starting in 2013, and the Ross Prize in Molecular Medicine.
